Cable XLPE insulation compound

Description

Grade 4234 is sioplas (two steps) silane XLPE compound and suitable for 1kv and below low voltage cable, it is composed by 95% silane crosslinkable low density polyethylene (compound A) and 5% catalyst (compound B). The product has outstanding performance in high speed extrusion, smooth cable surface, wild processing temperature, easy processing and convenient to use.

Standard

After crosslinked in the tepid water, the cable made from our product grade 4234 can comply with the standard of IEC60502-2004, GB/T12706-2002.

Typical values were tested on the 1mm sample strip by squeezing film extrusion after mixing compound of A& B (at percentage of 95:5) and be boiled in hot water at 90℃for four hours.

*Especially, these typical values were tested by press moulding sample under the condition of 180±2 ℃, 15min, and pressure over 15Mpa, then boiled in 90℃water for four hours.

Recommended Processing Technique

1. Extrusion Equipment

Most extruders for PVC and PE suit for 4234.

The recommended equipment and processing technique isas following.

Ratio of length and diameter 18—25:1

Diameter 45—120mm

Ratio of compressing 1.5—3.5

Ratio of elongation 1:1.0—1:1.5

Filtering mesh 40/60/40

2. Extruder processing temperature and other related settings

Temperature Setting: Specific processing temperature should be based on different equipment and pressing conditions, reference settings are asfollowing:

Feeding Section（℃）

Compression Section（℃）

Measurement Section

（℃）

Die head and Mould

（℃）

130~155

155~170

170~180

180~200

Die head setting: Squeezing extrusion style is recommended

Cooling water temperature: Should not beless than 25℃,gradual cooling water tank is recommended.

3. Crosslink

After extrusion and cooling, the cable can be crosslinked by immersed in hot water (90℃) or exposed in low pressure vapour. The time required for crosslink is based on the thickness of the insulation and the coil size, the thicker the insulation and the greater the coil size, the longer the crosslink time required. The crosslink time can be calculated according to the equation of 4hr/mm for 90℃.

Q: Four lines only reached a phase line, at the other end all charged, I use the digital pen! In addition, I often check the cable when the cable current through the dot digital pen voltage symbols sometimes have time to disappear, in other bare wires when the test keys are normal! What is this going on! Ask the heroes to give the younger brother a complete point of the answer! More: This is too difficult to give you a way to just try: with a fine wire rope, that is, lift the clothes on the stick so thick, the end of a bend, with a tape wrapped around the head, try can not wear, wear When the possibility of rotating wire rope, if you can go through the success of the half, the key is to use the wire through the more difficult, can only use the cord, hard-line 100% make life difficult.

Q: What machinery is required to make wire and cable?: Line pipe is poured before the concrete is laid on the cloth, fixed on the template or steel, pouring a need to install a class at any time to adjust its position!

Q: Ipad not charge how the matter. Said the cable or accessories have not been certified, and may not be able to cooperate with this ipad reliable work....: According to the "Power Engineering Cable Design Code" GB-. 5.3.3 only asked for the depth of the cable buried directly: drop the blue skin to the ground depth, not less than 0.7 meters; when located in the roadway or farmland Under the appropriate should be deepened, and should not be less than 1.0 meters. 5.4.3 protected pipe buried in the ground, should meet the requirements under the depth of the pressure and environmental corrosion resistance. Through the uneven settlement of the backfill section and other places to increase the force, it is appropriate to use steel. Another direct burial should be selected armor type.

Q: Rt, the charger did not change, has been no problem before, today just plugged into the charger, the results appear as if the problem, before the out of this problem, and now only ipad power off after the power can not be charged, and ipad start , Then immediately prompted the title, can not charge more: Budget 1W5 requires the whole machine to include the display of the monitor not too big too much Not used to more

Q: Do not know why not mislead. The The The The The Fire resistance is IECGBBS6387. GB is the general principle of flame retardant and fire resistant wire and cable, quoted the above criteria...........................: Directly to find Dell customer service bar, the general warranty period are free replacement, unless the insurance of the. You can extend the warranty period, it seems you like to do the experiment.

Q: IPhone mobile phone data cable can not charge the power, the above shows the cable or accessories not certified can not work with the iPhone,: Data line pregnant, I also appeared once for a data line on it.

Q: Apple 6 Charging Why always show this cable has not yet been certified: Cable and cable distinction In fact, "wire" and "cable" and there is no strict boundaries

Q: Wire and cable model ZD what does it mean: Wire pipe water problem: In fact, this problem is very serious, then this line should be scrapped or replaced, if you continue to reluctantly use not only to bring you the safety of trouble and the insulation of the wire dropped sharply! Because there is water it will lead to internal leakage can also make the wire heat caused by wire burning and trivial trivial accident, so be sure to take the necessary replacement! Supplement: the wire out of all, with the wire to grab the absorbent gauze and the like back to the twitching, many times for the gauze to dry the water, hair dryer toward the tube to heat the tube to dry and then re-layout of the new line.

Q: This cable or accessory has not been certified and may not be able to work with this iphone reliably: The operation of the hydraulic pipe is very simple to see it will engage in their own, embedded more simple, and then get the construction site in accordance with the requirements of the drawings put away, tied with tie wire on the OK Mouth up the pipe to use cement bag to prevent good, to prevent the infusion of concrete, so buried even if the end

Q: What are the T and T, s of the wire and cable test type?: The expression is not very clear, it should be said to wear a tube, if a single wear on the line 100. Outside diameter 60mm.
